Aaberg Exhaust Hood Interaction with a Wall

Popis výsledku v původním jazyce

The article deals with computational modelling and experimental research on the Aaberg exhaust hood and its interaction with an obstacle. The hood makes use of a radial jet to increase its suction effect in two ways. First, it constraints the suction toa hemisphere only; second, the jet entrains the surrounding fluid towards itself and to the hood exhaust opening as a consequence of the entraining process. The hood exhaust opening diameter was 80 mm, the supply flange diameter 200 mm and the supply slot width 4 mm. Speaking of the dimensions, the obstacle - a disc located in front of the hood and aligned with the jet principal axis - was of the diameter of 550 mm. First, pure radial jet flow was examined; second, the combined supply and extraction hood regime. The latter regime was featured by the inertial fluxes ratio (supply to exhaust) of 0.6. The obstacle location varied according to two schemes to map the hysteretic jet behaviour. Firstly, the obstacle was located so close to the
